ANALYSIS PROCEDURES

All peak descriptor data is saved on disk for correlation studies at a later time. Raw data is retained in computer memory for up to 8 h and can be saved on disk by keypress or mouse button click. Several formats are available for data analysis. The two most useful are graphical plots of activity direction versus time and activity peak (descriptor data timing, polarity, and shape data) versus time.

The activity direction versus time is not useful for pattern detection but does help determine the location of the activity. The peak-width change and directional movement is used to estimate the activity location. This procedure is more subjective than analytical but is useful to limit the search for reported severe weather.

The peak-tracking format traces a selected peak (weather formation) over a period of time. The event activity is used as criteria for the trace function, which finds matching directional peaks from each periodic data record and plots the activity, timing factor, polarity percentage, and pulse-shape percentages as a function of record (time). This format produces the patterns that are the basis for severe-weather detection and prediction. During real time, a peak can be selected by keypress or mouse click and tracked for up to 8 h. Archived data can also be analyzed in a similar manner.
